The Parliament of Scotland (Scots: Pairlament o Scotland; Scottish Gaelic: Pàrlamaid na h-Alba), also known as the Estates of Scotland, was the legislature of the Kingdom of Scotland from the 13th century until 1707. The parliament evolved during the early 13th century from the king's council of bishops and earls, with the first identifiable parliament being held in 1235 during the reign of Alexander II, when it already possessed a political and judicial role.
A unicameral institution, for most of its existence the Parliament consisted of the three estates of clergy, nobility, and the burghs. By the 1690s it comprised the nobility, the shires, the burghs, and various officers of state. Parliament gave consent for the raising of taxation and played an important role in the administration of justice, foreign policy, war, and the passing of a broad range of legislation. Parliamentary business was also carried out by "sister" institutions, such as General Councils or Conventions of Estates, which could both carry out much business dealt with by parliament, but lacked the powers and ultimate authority of a full parliament.
